1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.
6.2L fitted to a 1987 HMMWV. The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993. The 6.2L diesel emerged as a high-fuel-economy alternative to the V8 gasoline engine lineup, and achieved better mileage than Chevrolet's 4.3L V6 gasoline engine of the 1980s, at a time when the market was focused on power rather than efficiency.
The AJD is a family of V6 and V8 turbodiesel engines with a clean-sheet architecture and variable valve timing developed by Ford of Europe for its then-subsidiaries Jaguar and Land Rover, as well as for its partner PSA Group working under the Gemini joint development and production agreement.
Travelers' diarrhea (TD) is a stomach and intestinal infection. TD is defined as the passage of unformed stool (one or more by some definitions, three or more by others) while traveling. [2] [3] It may be accompanied by abdominal cramps, nausea, fever, headache and bloating. [3] Occasionally dysentery may occur. [5]
Fibromyalgia (FM) is a medical syndrome that causes chronic widespread pain, accompanied by fatigue, awakening unrefreshed, and cognitive symptoms.Other symptoms can include headaches, lower abdominal pain or cramps, and depression. [9]
DT and Td vaccines lack the pertussis component. [36] [37] [38] The Td vaccine is administered to children over the age of seven as well as to adults. It is most commonly administered as a booster shot every 10 years. [36] The Td booster shot may also be administered as protection from a severe burn or dirty wound. [36]
Tides cause changes in the depth of the marine and estuarine water bodies and produce oscillating currents known as tidal streams. The changing tide produced at a given location is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of Earth rotation and the local bathymetry .
